How does the brass pipe electrolysis purification work

Brass pipes can be purified by many methods. One of them is electrolytic purification by electrolysis. How does the brass pipe electrolysis purification work?

First, the thick copper with a relatively high copper content is first made into a thick plate, and it is used as an anode. In addition, pure copper is formed into a thin sheet, which can be used as a cathode, and the electrolyte can be used for sulfuric acid and copper sulfate. Mix together to use. After the electricity is turned on, the copper will move from the anode to the cathode by dissolving into copper ions. When it arrives, electrons will be generated, and the place where the cathode comes back will produce pure copper. We usually call it electrolytic copper. Impurities in the blister copper,like some iron and zinc, are more active elements that dissolve into ions together with the copper. Since these ions are more difficult to precipitate than copper ions, in the case of electrolysis, it is possible to prevent them from being precipitated from the anode by appropriately adjusting the potential difference.

Impurities that are relatively inactive compared to copper, like gold and silver, accumulate under the cell. Through this copper plate produced, we are generally called electrolytic copper, and its quality is very good, it can be used to make electrical products. After the electrolytic copper is processed, there will be very fine electrolytic copper powder.
